' DETACHABLE PLOWSHARE-SECURING MEANS.

Specification of Letters Patent. Patented Apr. 11, 1922.

Application filed October 12, 1916. Serial No. 125,173.

E State of Kentucky, have invented certain new and useful Improvements in Detachable Plowshare-Securing Means. of which the following is a specification.

This invention has relation to plow bodies. or bottoms as they are frequently called in the trade and particularly .to a mechanism for attaching the share to the frog, the sand mechanism being designed to permit the share to be most readily and conveniently removed and replaced or renewed. In the accompanying drawings, I have particularly illustrated the preferredembodiment of the invention and while I shall hereinafter describe this particular embodiment in detail, it nevertheless should be understood that it is merely exemplary and that changes may be "made in the details without departing from the spirit of the invention or the scope of the subjoined claims.

In the accompanying drawings, wherein like characters of reference denote corres ponding parts in the several figuresw plow body embodying the present improve- I11911tS;Wltl1 the several parts assembled and drawn together;

F 2 is a similar view, showing the share :and attaching'members separated from the remaining parts of the body but in .position to be assembled; I

F is a detail view, partly n 890M011,"

of the share-clamping means;

Fig. 4 is a sectional view of one of the spools'or sleeves, drawn to a larger scale than any of the preceding figures.

The plow body includes. as .usu aLa share,

boa-rd vB whose forward edge engages the faces of the share-member A and moldboard B and crosses the joint between said members, and further comprises a member D which lies against the inner surfaces of the share-member A and the landside C and crosses the joint at their abutting edges. E, in this particular exemplification of the invention, designates the forward edge of the plow beam, which lies against the inner surface of the member D of the frog The member D of the frog; is securely fastened to the moldboard B by suitable means, as a bolt and nut, for example, indicated at'Z). The landside C, member'D" of the frog and beam'E are securely fastened together by suitable means, as the'bolts and nuts, indicated at e, e, for example; and said member D and landside C, preferably, are fur ther secured to each other by suitable means, as the bolt and nut,'indicated at (Z; for example. The beam E isrconnected to the described by which theshare may be most conveniently and quickly removed or ap plied, and when applied will b'e and rigidly secured in place. I c

To this end th'e'forwa rd {edge of the mem her i D of the frog has slots 10. 1'0 with 'Fig. 1 is a perspectiveview of an inverted open forward ends, and the member A of the share has projections 11, 11 from its inner surface, which projections extend into the slots 10, 10 respectively, when the parts are assembled. T he free ends of these projections are provided with .heads l2, 12, which overlie the rear surface "of the menr ber D of the frog and are spaced therefrom. The heads preferably employedand which are shown best i1i.Fig-.2, are provided by flanges formed on theends of spools or earner attics.

moldboard B by a bracing-member E which is appropriately secured to both of these sleeves 12. and have beveled surfaces pre-r.

,sented toward the rear surface of the member Dcof the frog. Nuts 13 1'3 onthe outer comprising the members A and A"; a mold endsof the projections ll, ll are preferably employed to' held the spools or sleeves rear edge of the member A; a landside (7, .whose forwardedge engages the member A", V of the share; and a frog comprising a memher I)- which'lies against. the under sur aga1nst rearward displacement, These. spools ,or. sleeves are preferably rotata-- bly :inounted on the progections 11, 111" so that their cylindrical bodies, which in such 7. Q

case extend into the openings 10,10, will I 1 act as anti-friction rollersagainst the walls of the openings and hence guide the share to its place with a mlnnnum of frlction.

Aclamping means which co-operates with the projections 11 and spools 12 is employed to secure theshare removably to the frog. This clamping means comprises a head or member 11. whose opposite sides are recessed to form books at opposite sides of its forward end. and a rod 16 which is pivoted shown at 1? to the member 1%. at a point which is between the hooks and preferably rearward thereof. llhen the parts are assembled. the hooks 15 engage the spools or sleeve and lie tightly between the beveled under surfaces" of the heads 12 on the spools or sleeves and the rear surface of the frog. Their edges are beveled to correspond with the beveled under surfaces of the heads The rear end of the rod 16, when the parts are assembled, extends to the back end of the plow body and at this, readily accessible .place an appropriate holding device for the rear end of the rod, is provided. The bolding device herein exemplified. comprises a block 18 which is held in place against the beam E by the brace E. which also con nects the beam to the moldboard said brace bein shown as extending laterally from the beam and bolted to the block, as shown at 19. This block 18 is provided with. a slot 18 which receives the rear or upper end of the rod 16 and said end is provided with an appropriate fastening device,as the nut 16, for example.

20 and 21 designate elements which are secured to theinoldboard B and share-member A. respectively, adjacent to the edges thereof. The confronting edges of these elements are correspondingly beveled and are so correlated that they act to guide the share downwardly while the latter is being applied and secured to the body, and hence co-operate with the sleeves or spools 12 in guiding the share to its proper position with reference to the frog, moldboard, and landside. They also help to maintain the share against lateral displacement from its proper position in the use of the plow.

22 designates a projection from the landsii'lo side A of the share and 23 designates a recess which forms a shoulder at the w front edge of the member D of the frog.

This pin and shoulder cooperate with each other in preventing the share from losingits pitch or penetration.

In the operation of attaching the share to the plow body it is only necessary to place the share on the extreme forward point of the frog and slide it back in a line substantially parallel with the beam. In this movement of the share the bodies of the spools 12 enter the slots 10 in the frog and aid in guiding the share back to its proper position with relation to the moldboard and landside with a minimum of friction. V fhen the share has been moved back as far as it can be pressed by hand, the operator on gages the hooks 15 with the spools. This can be very conveniently accomplished by grasping the rod 16 near its threaded end and moving it until the hooks engage the spools. The threaded end of the rod is then placed in the slot 18 in the block 18, after which the nut is drawn tight, thus forcing the share to its working position. The beveling of the edges of the hooks 15 and flanges of the spools assure the clamping of the share tightly against the frog while the share is being drawn back to contact with the moldboard and landside.

It will be apparent that by slacking the nut 16 the rod 16 may be moved forward to release the member 1% from the share, and said rod may then be removed from the block 18. thus disconnecting the rod and member 1% from the plow body, as well as permitting the share to be removed.

The simplicity of the construction herein exemplified, its effectiveness as a means for securing a share to a plow body, and the ease and convenience with which it may be connected to and disconnected from the share and block and drawn tight to lock the share will be apparent from the foregoing description.

Having now described the invention and exemplified the preferred embodiment there of. what I believe to be new and desire to secure by Letters Patent is:

1. A plow body comprising a moldboard, a landside. a supporting frog extending beyond the edges of said moldboard and landside. a detachable share, a beam attached to said moldboard and said frog, and means formaintaining said share in contact with the edges of said moldboard and landsidc and against the face of the extended portion of said frog, said means comprising a tightener rod acting at one end upon said share and at its opposite end upon said beam. 7

2. A plow body comprising a moldboard, a landside. a supporting frog extending beyond the edges of said moldboard and landside, a detachable share having means for interlockingly engaging said moldboard and frog at a plurality of points, a beam attached to said moldboard and frog, a block carried by said beam, and a tightener extending from said block to said share to maintain said share in interlocking engagement with said moldboard. laudside and frog.

ln testimony whereof I alrlx my signature.
